You will get AI automation and API integration using n8n, Python, and Node.js
Project details
Are repetitive tasks consuming your team's time?
I build AI-powered automation, API integrations, and backend workflows that connect your business systems and reduce manual work.
Instead of simply creating an automation that works once, I focus on building reliable workflows that can handle real-world business scenarios such as API failures, invalid data, authentication, retries, logging, and changing inputs.
I can help you automate processes involving:
• REST APIs
• Webhooks
• n8n
• OpenAI and AI APIs
• Python
• Node.js
• CRM systems
• Databases
• SaaS platforms
• Google Sheets
• Email systems
• Internal business tools
• Third-party applications
Examples of automations I can build
Lead Automation
Website Form → API → CRM → AI Qualification → Sales Notification
Document Processing
Document Upload → AI Extraction → Validation → Database → Report
Customer Automation
New Customer → CRM → Account Creation → Email → Internal Notification
Data Synchronization
Application A → API → Data Transformation → Application B
AI Workflow
User Input → OpenAI → Business Logic → Database → Automated Response

Rawalpindi, Pakistan - 1:46 am local time
I help startups and growing businesses turn ideas, operational challenges, and early-stage products into scalable, production-ready software systems.
With over a decade of software engineering experience, my work goes beyond traditional full-stack development.
I can take ownership of the complete technical foundation of a product — from architecture and technology selection to backend systems, databases, APIs, AI integrations, DevOps, deployment, scalability, and engineering leadership.
I work especially well with founders and companies that need someone who can:
✓ Understand the entire system
✓ Make the right technical decisions
✓ Design a scalable architecture
✓ Build critical components
✓ Solve difficult engineering problems
✓ Lead developers through implementation
🛠️ WHAT I CAN HELP YOU BUILD
• SaaS platforms and startup MVPs
• Multi-tenant SaaS architectures
• AI-powered applications
• AI agents and intelligent workflows
• Business process automation
• n8n automation and integrations
• REST APIs and backend platforms
• Third-party API integrations
• Real-time applications using WebSockets
• Data processing pipelines
• Microservices and distributed systems
• Cloud and containerized infrastructure
• Internal business platforms
• Legacy system modernization
• High-performance backend systems
🤖 AI & AUTOMATION ENGINEERING
I don't approach AI as simply adding a chatbot to an application.
I integrate AI into the actual system architecture by combining:
• LLMs
• APIs
• Databases
• Business rules
• RAG
• Vector databases
• AI agents
• Workflow automation
• Human approval steps
• Validation
• Logging and monitoring
The goal is to build AI systems that are reliable enough for real business operations — not just demos or experimental prototypes.
AI & Automation Technologies:
OpenAI | Claude | Gemini | AI Agents | RAG | Embeddings | Vector Databases | n8n | Python | Node.js | Custom AI APIs
🏗️ SOFTWARE ARCHITECTURE & BACKEND ENGINEERING
I design systems with scalability, reliability, maintainability, security, and future growth in mind.
Core Technologies:
Node.js | TypeScript | Python | C# / .NET | REST APIs | WebSockets | Microservices | PostgreSQL | MySQL | MongoDB | Redis | Apache Kafka | MQTT | Docker | Kubernetes | CI/CD | Nginx | Caddy | Cloud Infrastructure
👨💻 HOW I CAN WORK WITH YOUR BUSINESS
🏛️ Software Architect
Design the technical foundation, system architecture, database structure, APIs, infrastructure, integrations, and scalability strategy.
⚙️ Lead Engineer
Build critical parts of the product while establishing engineering standards, architecture patterns, and development practices.
👥 Technical Lead
Convert architecture into executable development tasks, review implementations, solve technical blockers, and guide developers through delivery.
📈 Fractional CTO / Technical Advisor
Help founders make better decisions around architecture, AI adoption, infrastructure, scalability, development teams, and technology strategy.
💻 Hands-on Senior Developer
Step directly into the codebase when complex features, integrations, performance issues, architecture problems, or difficult bugs need to be solved.
🎯 WHERE I ADD THE MOST VALUE
I am most valuable on projects where the question is not simply:
"Can you build this feature?"
But rather:
"How should we build this system correctly?"
My goal is to help you build the right technical foundation, avoid expensive architectural mistakes, and create software that can continue evolving as your business grows.
If you're building a:
✓ SaaS product
✓ Startup MVP
✓ AI-powered platform
✓ Automation system
✓ API platform
✓ Multi-tenant application
✓ Complex backend system
…and need someone who can own both the technical direction and the implementation, let's discuss your project.
